straddle carrier
Straddle carriers play a central role in modern container terminals and yard work. A straddle carrier is a self-propelled vehicle that lifts containers by straddling them, and it moves stacks around truck lanes and storage blocks. Terminals use these machines for flexible container handling, and they support short transfer distances between quay, truck, and stack. The straddle carrier delivers adaptability and operational flexibility in mixed operating models that combine manual drivers and automation. Straddle carrier operations vary by terminal layout, and operators tune routes to reduce delays and energy consumption.
Key safety risks include load instability, collisions with other vehicles or stacks, and overturns during tight turns or adverse weather conditions. Sensors and vision systems help detect sway and incorrect pick-up, and they reduce the chance of a tipped load. For example, integrating CCTV-based analytics can yield visual confirmation of container position and truck driver behavior, and that data supports collision avoidance. Our platform integrates with VMS feeds so sites can publish events via MQTT for dashboards and operator alerts, and teams can use the same data for safety and operations.
Relevant data metrics for a straddle carrier include load weight, position, and speed. Weight cells report cargo mass, and GPS or RTLS provide precise position so control systems can enforce speed limits near truck lanes and stacks. Motion sensors monitor acceleration and tilt so alerts can trigger before an overturn occurs. Predictive maintenance relies on these metrics to forecast bearing wear and hydraulic failures, which reduces maintenance costs and downtime. The global safety analytics market for straddle carriers reached USD 524.7 million in 2024, and it is growing quickly as terminals invest in sensor ecosystems USD 524.7 million in 2024. Industry reports note that safety analytics “is revolutionizing container handling by not only improving safety but also enhancing operational efficiency and reducing costs” the integration of safety analytics into straddle carrier operations.
Design choices matter. Many terminals select diesel-powered straddle carriers in mixed fleets, and others shift toward electrification for low energy consumption and reduced operating costs. Straddle carriers don’t require fixed rails, and that adaptability reduces capital investment and allows rapid reconfiguration of truck lanes and yard layout. When you evaluate fleet upgrades, compare energy efficiency and maintenance costs. Providers such as Kalmar and Konecranes offer different operating models and control systems, and terminals should evaluate integration pathways with their existing VMS and OT stacks.
rtg crane
A typical RTG crane, or rtg for short, sits on rubber tires and serves high-volume stacking tasks at many container terminals. The rtg crane moves along rows to build a stack of containers, and it handles dense storage zones where container stacking and transshipment require reliable lift cycles. Operators value rtgs for high stacking capacity and for the ability to reposition them across the yard when layout changes or when handling peaks occur.
Common hazards include tyre wear, crane sway, and boom collisions with nearby stacks or quay equipment. Tyre wear increases rolling resistance and can impair steering, and heavy-duty lifts in crosswind conditions can amplify crane sway. Vision and sensor integration reduce these risks. For instance, tilt sensors, GPS tracking, and load cells feed data to collision detection logic and to predictive maintenance algorithms. Equipment vendors now add sensors that measure load weight and position in real-time so controllers can prevent overload and unsafe lift angles real-time data on load weight, position, and movement.
Advanced rtgs also link into yard control systems and wireless telemetry so managers can adjust speed limits in congested zones. Automated RTG features enable semi-automated lifts, and in some sites an automated rtg shifts containers with minimal operator input. These developments reduce accidents and lower maintenance costs because telemetry warns teams before critical components fail. RTGs are part of broader material handling solutions that include crane control systems, and those systems must integrate with VMS, PLCs, and other OT layers for safe operation.
Terminals aiming to enhance safety often deploy edge processing to keep video data on site and to maintain GDPR and EU AI Act readiness. Visionplatform.ai lets terminals stream structured events to dashboards and SCADA, and this provides immediate operator alerts and recorded evidence for incident review. The combination of sensors, vision, and control systems delivers measurable improvements in uptime and safety at ports and terminals, and it supports safer quay-to-stack transfers during peak periods sensor integration improves safety and uptime.

rubber tyred gantry crane
Rubber tyred gantry crane systems combine multiple sensor types and telematics to support safe handling and stacking. The system architecture typically includes load cells, tilt sensors, GPS or RTLS, camera arrays, and a central telematics server that aggregates telemetry in real-time. Onboard controllers stream events to edge servers, and gateways publish structured messages to BI and SCADA via MQTT or webhooks. This design keeps critical data local while enabling operational dashboards and maintenance planning.
Data streams for safety analytics focus on motion, weight, and location. Motion sensors report acceleration and sway, and load cells report container mass and alert on overload. Cameras add visual context so analytics can confirm correct container dimensions and detect anomalies such as shifted cargo units or misaligned picks. Together, these feeds let operators and supervisors see when a lift could create instability near a busy stack, and they enable the enforcement of geo-fencing rules near truck lanes and quay edges.
Predictive maintenance uses algorithms to forecast failures by analyzing vibration, temperature trends, and load cycles. Machine learning models trained on historical failure records detect patterns that precede gearbox or hydraulic problems. These algorithms reduce maintenance costs and support safer crane operation by scheduling interventions before breakdowns cause unsafe conditions. Industry providers emphasize that predictive systems reduce unexpected downtime, and that predictive alerts can lower maintenance costs while extending component life straddle carrier market growth and related segments.
Rubber-tyred gantry cranes and rubber-tired gantry cranes require careful configuration. Dock managers must integrate control systems with terminal operating systems and with camera-based sensors to get end-to-end visibility. Our company helps terminals deploy edge safety detection and to turn existing CCTV into an operational sensor network so yards can reuse VMS footage for both security and operations edge safety detection and AI. This approach keeps data in place and speeds model tuning for specific handling operations.
straddle carriers and rubber tyred
Integrating analytics across mixed fleets of straddle carriers and rubber tyred equipment gives terminals a unified safety picture. Data fusion combines position, motion, and weight streams with video events. When systems correlate a moving straddle carrier with a nearby rtg, they can trigger collision-avoidance alerts that reach operators and fleet managers. That cross-equipment view helps terminals optimise truck lanes and stack sequencing for better throughput.
Data fusion enables yard optimisation as well. Combining container position data with live video events and truck arrival schedules reduces wait times at the gate and improves container moves per hour. Shared dashboards present the fused view to supervisors, and operators receive targeted alerts via HUDs or mobile devices so they act quickly. Visionplatform.ai streams events into dashboards and into business systems, and that makes camera-based detections usable beyond security for terminal operations and for BI.
Shared dashboards and operator alerts must be simple and actionable. For example, a collision warning should include the offending vehicle, the container ID, and the recommended action. These alerts are most effective when they tie to geo-fencing rules and to pre-set speed limits. The platform can also produce daily KPIs that show lead times, container stacking times, and maintenance flagging so managers can evaluate route changes and capital investment choices. Integrating analytics across fleets delivers improvements in operational flexibility and in safety outcomes, and it helps terminals meet SLAs for truck drivers and for transshipment flows.

crane operation
Analytics support many safety protocols in crane operation, including geo-fencing and dynamic speed limits. Geo-fencing prevents cranes and straddle carriers from entering restricted zones near quay edges and near critical stacks. Speed limits adjust automatically when the system detects truck congestion or when weather sensors report high winds. Decision-support tools deliver operator HUDs and mobile alerts that highlight the safest action and that reduce human error.
Operators also gain from decision support that shows predicted interference between lifts. When two pieces of handling equipment approach the same stack, analytics propose an alternate sequence to avoid delays and potential collisions. This capability reduces incidents and improves container moves per hour, and it directly impacts operating costs and maintenance costs. The result is better operational efficiency and safety, and terminals see measurable reductions in incidents.
One case study from a major port shows improved throughput and fewer incidents after deploying integrated analytics and camera-as-sensor workflows. The terminal combined RTG sensors with vision-based event streams and reduced unsafe lift events by a material margin. In practice, this meant fewer emergency repairs and lower capital investment in spare parts. Terminals that adopt these systems also lower energy consumption by smoothing motion cycles and by reducing idle times for diesel-powered equipment.
